As we approach the end of this earnings season, investors will possibly heave a sigh of relief seeing that the going was not as bad as expected. Of the total S&P500 members, 88% will have reported results by the end of this week, thus making the picture even clearer. A major reason behind companies posting better-than-expected results during the quarter is perhaps already lowered expectations since the beginning of the earnings cycle. The recent decline in the U.S. dollar also aided matters. As a result, although estimates for the second quarter are still witnessing downward revisions, the decline is not as severe as last quarter.Meanwhile, the medical sector started the year on a shaky note due to the sell-off witnessed by the biotech sector in the second half of 2015. Nevertheless, things are definitely looking up as the sector is still poised to beat both earnings and revenues estimates on an overall basis. In fact, as per our Earnings Trend report, the medical sector is one of the few sectors slated to record earnings growth this season.What to Expect From These Drug Stocks?Johnson & Johnson JNJ kick-started the season on a positive note, wherein its earnings surpassed expectations and the company raised its outlook for the year. Abbott Laboratories ABT followed suit. Swiss oncology major Novartis NVS, however, missed estimates. On the other hand, biotech majors Biogen BIIB and Amgen AMGN topped expectations, while industry bigwig, Gilead Sciences GILD disappointed investors’ expectations.However, a few key stocks are still yet to report results. Let’s see how these stocks are poised ahead of their scheduled announcements tomorrow.Geron Corporation GERN is scheduled to report first-quarter 2016 results on May 5.
